Abstract: One of the engineering challenges is understanding natural phenomena, analysing systems, and using results found as needed based on scientifically approved processes. In this study, two methods are analysed, the finite element method and the experimental method to know which method gives the precise results compared to the other. The case study considered in this work is a 3D printed structure that was modelled as a two-story shear building system with an irregular torsion. The finite element method is computed as a numerical model that is developed by using SAP2000. The experimental method is computed by collecting modal parameters data at the laboratory by ambient vibration and white noise test, then modelled by ARTeMIS pro, based on numerical techniques for the identification of systems in the time domain. The results obtained from the numerical and experimental models are compared then found the most accurate method.
